(答案→)keep 解析：短文大意：本文主要介绍了饮食和锻炼对人体健康的重要作用，并分别就饮食和锻炼两个方面进行了具体的说明和讲解注意事项等。【小题1】本句大意为：事实是，健康的饮食和经常锻炼是保持健康的唯一方法。保持健康的表述应该是“keep fit”，故答案为keep。【小题2】本句为一对比题型，后面说的是男孩一天需要的卡路里数量，自然前面就应该是女孩需要的营养数量，故答案为girls。【小题3】根据后面的男孩需要2800卡路里营养，而前面说女孩需要2200卡路里可知男孩比女孩需要的营养数量要多，故答案为more。【小题4】紧接上面的叙述，此处应该是说这些热量有一半来自于大米、面包、蔬菜和水果。故描述的来源问题，答案为from。【小题5】前面说你每天需要喝6-8杯水，自然。喝足够的水能够改善你的皮肤和发质。故答案为enough。【小题6】本段中重点描述的是锻炼带给人健康的好处，自然，锻炼有助于你看起来和感觉更健康。故答案为Exercise/Exercising。【小题7】根据本句的结构可知，它重点是考查花费时间做某事的用法，即spend time （in）doing sth，故答案为spend。【小题8】体内产生使人放松的因素是在锻炼时出现的，故答案为When，注意句首单词的首字母要大写。【小题9】锻炼能使人感到全身轻松，根据所给的首字母可推测出故答案为relaxed。【小题10】锻炼有助于改善你晚上的睡眠和增加工作学习时的注意力，pay attention to意为“注意”，后面没有宾语时要省略介词to，故答案为attention。
